Functional Notes
Use secondary IP addresses to allow dual subnets on a single interface (when you need more IP
addresses than the primary subnet can provide). When using secondary IP addresses, avoid routing loops
by verifying that all devices on the network segment are configured with secondary IP addresses on the
secondary subnet.
